If traveling with Accels I'd keep the fin inserts in them. The material is rather thin. I had a pair in storage that must have had something pressing against them and it created a crease in the foot pocket that could only be removed by applying heat. I think the F2s are a more robust travel fin being made from much thicker monoprene. YMMV.
Underwear works nicely as an insert, as well
